Each person in their life sooner or later faced with a choice. What would he difficult appeared, people normally choose. From childhood we dreamed of becoming adults, make family, go to work like our parents. But childhood passes, and there comes time to think seriously: «What I want to become?». Long thinking, I decided to become a medical sister. Than I was attracted by this profession? First of all I always wanted to help people, because it's wonderful when people come to your people with their complaints in the hope of assistance, and very nice to know that somebody needs you. Medical sister is one of the noblest professions. It should always be kind and merciful, because the work that she is doing, relieves suffering of the patient. Health care workers, people always relate specifically, they valued and respect. Early in the H1H century, this profession is caused universal admiration and respect. Nurses also called the sisters of mercy, they unselfishly were willing to help wounded soldiers, they went to the front and created there, the aid organizations to the military. Eventually destination medical sisters have changed, but they still demanded. I think, in the work of the medical sisters attracts me to communicate with people. Because every day I will learn more and more, I will take part in their fate at least, because they trusted me with their health and life. Nurse, my opinion - the most interesting, necessary and important profession. Interesting and very responsible. When I feel that I must do something useful for people, I understand that some people need and, therefore, I do not live in vain!
Предположим, что пятиугольник только один. Тогда количество вершин у семиугольников равно 34 − 5 = 29. Этого не может быть, потому что число 29 на 7 не делится.
Если пятиугольников два, то количество вершин у семиугольников равно 34 − 10 = 24, чего быть не может.
Если пятиугольников три, то количество вершин у семиугольников равно 34 − 15 = 19, чего быть не может.
Если пятиугольников четыре, то количество вершин у семиугольников равно 34 − 20 = 14. Значит, может быть два семиугольника.
Если пятиугольников пять, то количество вершин у семиугольников равно 34 − 25 = 9, чего быть не может.
Больше пяти пятиугольников быть не может.
Ответ: 2.
